Films are not always organic, fully formed creatures when they are written. The script can change as the film is made and actors, directors and producers can make decisions about where the project is going which completely remixes the process. And sometimes, actors decide to say or do something wholly unexpected, resulting in pure magic.
Be it fun one-liners or actions which caught others off guard, the following list delves deep into the times actors went off script (or conspired with the director) to add another level to the film they were making. Many of the films featured are classics, and all offer something wonderful and unique thanks to some ballsy performing from the actors involved.
In most cases, what transpired from these bursts of creativity are scenes nothing short of perfect borne from the kind of scenario that comes along once in a lifetime. Genre, too, is no barrier to these moments of genius - horror, comedy, action and drama, every one gets a chance to shine. Actors may go too far with their ideas, but these are often the most impressive ones, and it's safe to say audiences are glad some performers are willing to take the risk.
